Description

Technical Field

[0001] This application relates to the field of linear guide technology, and in particular to a linear guide with a cleanup function. Background Technology

[0002] Linear guides are guiding devices used in precision mechanical motion. They mainly consist of two parts: a guide rail and a slider. The guide rail is typically a high-precision track with excellent straightness, usually manufactured using high-precision machining processes to ensure its surface flatness and straightness accuracy. The slider is the component that works in conjunction with the guide rail. It contains rolling elements such as balls or rollers that roll between the slider and the guide rail, enabling the slider to achieve high-precision linear motion on the guide rail. Linear guides have wide applications in industrial production. For example, in CNC machine tools, they ensure that the cutting tool moves along a precise straight trajectory, thereby guaranteeing machining accuracy. In robotic arms of automated equipment, linear guides help the various joints of the robotic arm to extend and retract precisely, enabling the robotic arm to accurately grasp and place objects. At the same time, linear guides also have advantages such as low coefficient of friction, high precision retention, and long service life, which can effectively improve the working efficiency and stability of equipment.

[0003] Currently, existing linear guides often have relatively simple structures in practical applications. In most cases, they lack corresponding cleaning mechanisms. Even those with cleaning mechanisms often employ simplistic methods, typically involving a drive motor rotating a threaded rod. This rotation causes a slider to move linearly within the receiving cavity, while the slider moves a cleaning plate synchronously. The cleaning plate then cleans the surface of the threaded rod with brushes. However, this overall cleaning process has significant shortcomings. It relies primarily on a screw-driven slider to move the brushes, which are not actually moving during this process; they merely perform lateral displacement. This method is inefficient and ineffective at removing stubborn impurities. Furthermore, it fails to clean the inner walls of the guide. Excessive impurities on the inner walls can severely impact the normal operation of the linear guide. In conclusion, existing linear guides exhibit certain deficiencies in cleaning, necessitating urgent design improvements to enhance their cleaning effectiveness and performance.

The lead screw is rotatably connected to the inside of the guide rail body, and a slider is threadedly connected to the outer surface of the lead screw. The slider is slidably connected to the inside of the guide rail body, and cleaning mechanisms are installed on both sides of the slider. The outer side of the cleaning mechanism is in contact with the inner wall of the guide rail body, and the inner side of the cleaning mechanism is in contact with the outer surface of the lead screw.

[0006] The cleaning mechanism includes a transmission assembly and a hinge. The transmission assembly is fixedly connected to the top two sides of the guide rail body, and the hinge is fixedly connected to the front and rear ends of both sides of the slider. The cleaning assembly is movably installed on the front and rear ends of both sides of the slider through the hinge. The top of the cleaning assembly and the bottom of the transmission assembly are connected by transmission.

[0007] In one feasible implementation, the transmission assembly includes a support arm fixedly connected to the middle of the top two sides of the guide rail body. A top plate is fixedly connected to the end of the support arm away from the guide rail body. A rack is fixedly connected to the bottom of the top plate, and the bottom of the rack is drively connected to the top of the cleaning assembly.

[0008] In one feasible implementation, the cleaning assembly includes a gear rotatably connected to the inner side of a hinge. Cleaning brushes are mounted on both sides of the gear via shafts. The cleaning surface of the cleaning brush near the lead screw is in contact with the outer surface of the lead screw, and the cleaning surface of the cleaning brush away from the lead screw is in contact with the inner wall of the guide rail body.

[0009] In one feasible implementation, the lower end of the slider has a convex cross-sectional shape, the inner cross-sectional shape of the guide rail body is rectangular, the lower end of the slider is slidably connected to the inside of the guide rail body, and a wear-resistant pad is fixedly connected to the outer surface of the slider.

[0010] In one feasible implementation, a device connecting plate is fixedly connected to the top of the slider, and mounting holes are provided at the four corners of the bottom of the device connecting plate.

[0013] This application provides a linear guide rail with a cleaning function. A drive motor rotates the lead screw within the guide rail body, driving the slider to slide and causing the hinge to move laterally. Because the support arm rack is fixed, the gear rotates, which in turn drives the cleaning brush. The inner cleaning brush adheres to the outer surface of the lead screw, while the outer cleaning brush adheres to the inner wall of the guide rail body. The brush rotates simultaneously with the lateral displacement, improving cleaning efficiency and effectively cleaning stubborn impurities. Furthermore, a storage drawer is provided within the storage slot. During cleaning, dust and impurities fall into the drawer, which is magnetically sealed to the guide rail body and stably installed in the storage slot. When cleaning is needed, the drawer can be pulled out by pulling out the magnetic sealing plate, facilitating dust collection and improving ease of use. Attached Figure Description

[0027] Example

[0028] refer to Figures 1 to 5 This embodiment of a linear guide rail with a cleaning function includes a guide rail body 100. A drive motor 200 is fixedly connected to one side of the guide rail body 100. A lead screw 300 is fixedly connected to one end of the output end of the drive motor 200 through the guide rail body 100. The lead screw 300 is rotatably connected to the inside of the guide rail body 100. A slider 400 is threadedly connected to the outer surface of the lead screw 300. The slider 400 is slidably connected to the inside of the guide rail body 100. Cleaning mechanisms 500 are installed on both sides of the slider 400. The outer side of the cleaning mechanism 500 is in contact with the inner wall of the guide rail body 100, and the inner side of the cleaning mechanism 500 is in contact with the outer surface of the lead screw 300.

[0029] The cleaning mechanism 500 includes a transmission assembly 510 and a hinge 520. The transmission assembly 510 is fixedly connected to the top two sides of the guide rail body 100. The hinge 520 is fixedly connected to the front and rear ends of both sides of the slider 400. The cleaning assembly 530 is movably installed on the front and rear ends of both sides of the slider 400 through the hinge 520. The top of the cleaning assembly 530 and the bottom of the transmission assembly 510 are connected by transmission. The drive motor 200 on one side of the guide rail body 100 can provide power to the lead screw 300, so that the lead screw 300 rotates in the guide rail body 100, thereby driving the slider 400 to slide in the guide rail body 100. The cleaning mechanisms 500 on both sides of the slider 400 are cleverly connected to the slider 400 through the transmission assembly 510 and the hinge 520. During use, the outer side of the cleaning mechanism 500 is in contact with the inner wall of the guide rail body 100, and the inner side is in contact with the outer surface of the lead screw 300, enabling comprehensive cleaning of both the guide rail body 100 and the lead screw 300. This design not only improves the cleaning efficiency of the linear guide rail, but also effectively removes stubborn impurities, maintains the linear guide rail in good working condition, extends its service life, and provides users with a more stable and reliable user experience.

[0030] The transmission assembly 510 includes a support arm 511, which is fixedly connected to the middle of the top two sides of the guide rail body 100. A top plate 512 is fixedly connected to the end of the support arm 511 away from the guide rail body 100. A rack 513 is fixedly connected to the bottom of the top plate 512. The bottom of the rack 513 is connected to the top of the cleaning assembly 530 via a transmission connection. The cleaning assembly 530 includes a gear 531, which is rotatably connected to the inner side of the hinge 520. Cleaning brushes 532 are mounted on both sides of the gear 531 via shafts. The cleaning surface of the cleaning brush 532 near the lead screw 300 is connected to the lead screw 300. The outer surface of the linear guide 530 is fitted with the cleaning brush 532 on the side away from the lead screw 300, and the cleaning surface of the brush 532 on the side away from the lead screw 300 is fitted with the inner wall of the guide body 100. The support arm 511 in the transmission assembly 510 is fixed in the middle of the top two sides of the guide body 100, providing stable support for the top plate 512. The rack 513 at the bottom of the top plate 512 is connected to the cleaning assembly 530. The gear 531 in the cleaning assembly 530 is rotatably connected to the inner side of the hinge 520. The cleaning brush 532 is installed on both sides of the gear 531 through shafts, so that the cleaning brush 532 on the side closer to the lead screw 300 can fit tightly against the outer surface of the lead screw 300. The cleaning brush 532 on the side away from the lead screw 300 can fit against the inner wall of the guide body 100. This design can achieve comprehensive cleaning of the lead screw 300 and the inner wall of the guide body 100 when the linear guide is working, effectively removing impurities. This maintains the good operating condition of the equipment and extends the service life of the linear guide.

[0031] The lower end of the slider 400 has a convex cross-section, while the inner cross-section of the guide rail body 100 is rectangular. The lower end of the slider 400 is slidably connected to the interior of the guide rail body 100. Wear-resistant pads are fixedly connected to the outer surface of the slider 400. A device connecting plate 600 is fixedly connected to the top of the slider 400. Mounting holes 700 are provided at the four corners of the bottom of the device connecting plate 600. Fixing plates 800 are fixedly connected to both sides of the bottom of the guide rail body 100. The ends of the fixing plates 800 are also... The linear guide 400 is provided with mounting holes 700, which are countersunk holes. The lower end of the slider 400 has a convex cross-section, which matches the rectangular cross-section of the guide rail body 100. This makes the sliding of the slider 400 within the guide rail body 100 more stable, less prone to wobbling or deviation, and ensures the accuracy of the linear guide's operation. The wear-resistant pads fixed to the outer surface of the slider 400 reduce friction between the slider 400 and the guide rail body 100, extending the service life of both. The device connecting plate 600 at the top of the slider 400 and the mounting holes 700 at the four corners at the bottom facilitate connection and installation with other equipment, improving the versatility of the linear guide. The fixing plates 800 fixedly connected to both sides of the bottom of the guide rail body 100 and the mounting holes 700 at both ends also facilitate the installation of the linear guide. The countersunk mounting holes 700 make the installation more aesthetically pleasing and secure, reducing the possibility of loosening during installation and enhancing the stability of the linear guide during use.

[0032] The bottom of the guide rail body 100 has a storage groove 900, and a storage drawer 1000 is slidably connected inside the storage groove 900. The top of the storage groove 900 is connected to the bottom of the guide rail body 100. A magnetic sealing plate 1100 is fixedly connected to the outer end of the storage drawer 1000, and the magnetic sealing plate 1100 covers the outer end of the storage groove 900. The storage groove 900 at the bottom of the guide rail body 100 and the internally slidably connected storage drawer 1000 cooperate with each other. During the operation of the linear guide rail, the impurities cleaned by the cleaning mechanism 500 can fall into the storage drawer 1000, realizing the centralized collection of impurities and preventing impurities from accumulating inside the guide rail body 1000 and affecting the normal operation of the linear guide rail. The magnetic sealing plate 1100 at the outer end of the storage drawer 1000 can tightly cover the outer end of the storage groove 900. Magnetic adsorption ensures that the storage drawer 1000 is sealed when not in use, preventing impurities from re-entering the guide rail body 100 and also preventing the storage drawer 1000 from accidentally sliding out, thus ensuring the overall cleanliness and stability of the linear guide rail.

[0033] The operating principle and advantages are as follows: This linear guide has a unique and efficient cleaning function during actual application. First, the drive motor 200 can be started to run. After the drive motor 200 runs, it can drive the lead screw 300 to rotate. The lead screw 300 is rotatably connected to the inside of the guide body 100. At this time, the lead screw 300 rotates inside the guide body 100, thereby synchronously driving the slider 400 to slide inside the guide body 100. As the slider 400 inside the guide body 100 slides laterally, it can synchronously drive the hinges 520 on both sides of the slider 400 to move laterally. It is worth noting that the gear 531 and rack 513 inside the hinge 520 are in a meshing connection. As the hinge 520 drives the gear 531 to move laterally, the rack 513 on the support arm 511 remains stationary, causing the rack 513 to drive the gear 531 to rotate. The rotation of the gear 531 then synchronously drives the cleaning brush 532 to rotate. The inner cleaning brush 532 is in close contact with the outer surface of the lead screw 300, while the outer cleaning brush 532 is in contact with the inner wall of the guide rail body 100. By rotating the cleaning brush 532 through the gear 531, it can assist in the efficient brushing and cleaning of the outer surfaces of the guide rail body 100 and the lead screw 300. Unlike the traditional method, the cleaning brush 532 itself is rotating during the lateral displacement, which allows it to more efficiently brush and clean the inside of the lead screw 300 and the guide rail body 100, improving cleaning efficiency, especially for stubborn impurities.

[0034] Furthermore, the inclusion of a storage drawer 1000 within the storage slot 900 greatly facilitates cleaning. During cleaning, the cleaning brush 532 cleans the inside of the guide rail body 100 and the outer surface of the lead screw 300, collecting dust and impurities into the drawer 1000. In use, the drawer is held in place by a magnetic sealing plate 1100, allowing it to be stably installed inside the storage slot 900. To clean, simply pull out the magnetic sealing plate 1100 to remove the drawer 1000. This design facilitates quick and easy collection of dust during use, significantly improving overall ease of use and providing users with a more efficient and convenient experience.
